SQUARE BOTTLE MANUFACTURED FROM SYNTHETIC RESIN - Disclosed herein are bottle-shaped containers having a trunk portion approximating a square. The trunk portion comprises four tabular side walls arrayed about a center axis and four corner walls connected to adjacent side walls in a corner-cutting form. The width of the corner walls expands from the top end and the bottom end toward a position about midway between the top end and the bottom end. By making the widths of the side walls and the corner walls about equal at a location about midway between the top portion and the bottom portion, the distance between the corner walls in mutual opposition with respect to the center axis can be decreased, forming a waist portion.
